Substitute Part Grouping Explanation

Substitution eligibility for the CDV30FK182FO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1800 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 2.5 kV (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 0.437" / 11.10 mm (exact match required)
• Physical Dimensions: 0.811" L × 0.370" W / 20.60 mm × 9.40 mm (exact match required)

The substitute part CDV30FK182FO3F meets all electrical and mechanical parameters identically to the main part. Differences exist only in regulatory compliance status, which does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

CDV30FK182FO3F is a direct functional equivalent to CDV30FK182FO3 for all electrical and mechanical applications. Selection between these parts should be based on regulatory and compliance requirements:

• Select CDV30FK182FO3 for applications where RoHS non-compliance is acceptable and REACH-affected material status is permissible.
• Select CDV30FK182FO3F for applications requiring ROHS3 compliance and REACH-unaffected material status.

Both parts are active products from the same manufacturer and series. Inventory availability should be evaluated based on project timeline and volume requirements.

Frequently Asked Questions (FAQ)

Q: Are CDV30FK182FO3 and CDV30FK182FO3F electrically identical?

A: Yes. Both parts have identical capacitance (1800 pF), tolerance (±1%), voltage rating (2.5 kV), temperature range (-55°C to 125°C), and all other electrical specifications.

Q: Can these parts be used interchangeably on a PCB?

A: Yes. Both parts have identical physical dimensions, lead spacing (0.437" / 11.10 mm), and radial through-hole mounting configuration. No PCB layout modifications are required for substitution.

Q: What is the difference between these two parts?

A: The primary differences are regulatory compliance status. CDV30FK182FO3F is ROHS3 compliant and REACH unaffected, while CDV30FK182FO3 is RoHS non-compliant and REACH affected. Electrical and mechanical performance are identical.

Q: Which part should I specify for new designs?

A: Selection depends on end-use market and regulatory requirements. For applications subject to RoHS3 or REACH restrictions, specify CDV30FK182FO3F. For applications without these restrictions, either part is acceptable.

Q: Are there any performance differences in high-temperature or high-voltage applications?

A: No. Both parts operate identically across the full temperature range (-55°C to 125°C) and voltage rating (2.5 kV). Operating temperature and voltage specifications are identical.

Q: What is the lead spacing for these radial capacitors?

A: Lead spacing is 0.437 inches (11.10 mm) for both parts. This dimension is critical for PCB footprint compatibility.
